IMPROVEMENT IN TEA-KETTLES.

Specitication forming part of Letters Patent No. 4,417, dated March 14, 1846.

To all whom t may concern.'

Be it known that I, EZRA RIPLEY, of Troy,

in the countyof Rensselaer and State of New York, have invented a new and useful Improvement in TeaKettles, whereby they can be molded with greater facility and consequent cheapness; and I do hereby declare that the following is a full, clear, and exact description of the principle or character thereof, which distinguishes it from all other things before known, and of the manner-of making or molding the same, reference being had to the accompanying drawings, in which- Figure lis a representation of the kettle; Fig. a, a vertical section thereof in the mold, and Fig. 3 a horizontal section taken at the line X X of Fig. l.

The same letters indicate like parts in all the gurcs.

A tea-kettle is a culinary implement of a definite nature, distinctfrom all others, in which water is to be boiled, to be poured therefrom through a spout projecting from the bulge or largest diameter of the body, the upper part which receives the lid being of a reduced diameter, to prevent the wat-er from running out at the top when inclined to discharge the water from the spout. As heretofore and now generally made, the spout is a circular tube projecting from the bulb or larger diameter of the body in a curved line, which can only be cast by means of a hard sand core attached to and projecting from the body ot the mold, and thereforeattended Vwith much difficulty.

To avoid these objections is the-object of my improvement, which consists in making that part of the spout which starts from the body of the kettle to extend from the greatest diameter or bulge of the body up to within a short distance of Jthe top, leavingl only suiticient space between the top of the spout and the top ofthe kettle to give the necessary strength of metal, the sides of the spout being curved so as to gradually run. into the curve of the body of the kettle. By this form of the spoilt I am enabled to get the necessary area in the cross-section of the spout to give the requisite strength to support a green sand core for the formation of the spout, so

that the mold can be made in two parts, sepa-k rated by a vertical plane passing through the middle of the body and spout. The two ears to which the bail is 4atixed are cast at the same time, one of these being a projection from the top of the spout. Another and important ad- ,vantage arises from this mode of making teakettles, which cannot be attained by the old method, and that is the glazing of the inside of the spout to prevent the injurious action of oxidation. f

In the accompanying drawings, a represents the bulge or greater diameter of the body of the kettle, from which thelower curve of the spout Z) commences, and c the top or smaller diameter, to which is fitted the cover. From the lower part of the upper rim or smaller diameter, c, commences the upper curve of the spout, which extends to the opening c thereof.

rihe swell of the sides of the spout (represented at j' f) gradually runs into the curve of the body, to give the necessary strength to the junction of the core with the body of the mold, giving a graceful curve, adding beauty to strength. It will be evident that the form of this spout may vary considerably within the range of the principle` pointed out above, which consists, simply, in extending that part ot' the spout which starts from the body ofthe kettle to extend from the bulge or larger diameter to within a short distance of the top, so that the necessary area can be obtained for molding with a green sand core, whilea channel .is formed from the bulge of the body for the delivery of the water without the danger of spilling the water from the top of the body. This mode of forming the spout admits of molding by means of a pattern divided into two parts by a plane passing through the middle of the body and spout and through the ears, instead ot' by a plane at right angles to the spout, whereby the parts for molding the ears make part of the pattern, instead ot' requiring the mold to be altered for this purpose after the molding has been effected; and

the core for the body and spout is made in one piece instead of two, the space between the end of the spout and the top of the kettle being so short and the area of the junction of the two S0 great :1S 130 give ubundmlt suppori i ci" the top, whereby, in molding, the spout een tet-libia piu'b which forms the spout. be foi-ined by means Ot' a. green instead of a W'hat I claim as my invent-ion, and desire dry sand core7 as hcvein described. t0 secure by Letters Patent, is-
